Description

The invention relates to a pyrotechnic warhead or a warhead in a projectile, in particular, in the medium-caliber range.

Known types of ammunition often do not have sufficient penetrating power against modern armored systems. New types of munitions, such as REGEF-type munitions, must, in addition, achieve a significant fragmentation effect after passing through the target object.

Documents EP 1 316 774 VI, EP 1 000 311 B1 describe the so-called RE E-effect, which is used in the so-called REGE-T or REGE-T Rep projectiles. Ammunition of the type is also known

NO, when using which the acceleration of fragments is achieved due to the detonated transformation of secondary explosives.

The lateral acceleration due to the REI of the E-effect is set, mainly, due to the speed of the target. The higher the firing range, the smaller the effect. As a result, the cone of fragmentation becomes smaller. This is, in practice, the process of weakening the effectiveness of the projectile on the target.

The acceleration of fragments when using shells or munitions of the NE type (Nidp Ehriovime), such as high explosive grenades, is known to be very high. However, explosive substances are used, which increase the safety risk of such a projectile during the entire cycle of combat service.

Separate components of the ignition device are additionally required.

Ammunition type MR. (Milly-Rigrose) have the same problems as NE ammunition, even if no fuze rounds are used in this case. However, there is the problem of unspecified states, such as an exploded projectile or changes in the weapon's operation with feed problems.

Shells of the NE type, as well as MR, contain, as a rule, secondary explosives, which are set off with the help of a pyrotechnic set (MR) or a special incendiary device (NE).

Document EP 0 531 697 B1 discloses a universal projectile that has a shell, a penetrator and at least one incendiary charge. The incendiary charge is compressed along its entire cross section.

From document CE 10 2005 039 901 B4, a projectile with an external and/or central

With a penetrator. The outer penetrator, as well as the central penetrator, can be formed using a subshell. Although this type of projectile is close to the one used in practice, in this case, the effectiveness or power of hitting the target depends on the speed of the projectile at the moment of meeting the target.

In this case, the invention sets its task to create a projectile that overcomes the indicated shortcomings.

The task is solved with the help of the features of clause 1 of the claims. Preferred implementation options are contained in the dependent clauses of the claims.

The idea behind the invention is to provide a projectile that, without the use of an explosive substance and an incendiary device, significantly increases the side fragmentation effect, compared to the REGE type projectile. They strive for a combination of a pyrotechnic warhead with a proven REGE effect, in particular, in a medium-caliber projectile.

Shells without explosives are known from OE 10 2012 023 700 AT, as well as from OE 10 2013 002 119 AT. A projectile without explosives conforming to OE 10 2012 023 700 A1 when hitting a target releases a combustible material or a mixture of combustible materials as a flammable fuel-air mixture. This mixture is subject to spontaneous transformation with the help of at least one explosive-free, spark-generating ignition mechanism caused by a rupture upon impact. Such projectiles without explosives are designed to create optical and thermal target indicators.

When implementing this proposed idea, a non-detonating pyrotechnic set is considered as a combat mass. Metal powder/oxidizer is preferably provided as a pyrotechnic set. When hitting the target, the shock wave works to form fragments and at the same time activates the warhead, so that the expanding gases of the pyrotechnic set additionally accelerate the surrounding fragments of the shell of the projectile in the lateral direction, and depending on the firing range and, that is, the speed of the projectile at the moment of meeting the target. At the same time, an oxidation-reduction reaction is used, in which, due to the chemical reaction of the pyrotechnic set, an instant exothermic oxidation-reduction reaction takes place, in which the released gas strongly expands under the influence of temperature and, thereby, causes an explosive force.

Due to the use of a redox system or redox systems, a certain secondary effect of a shock wave can be obtained. Pyrotechnic warhead can, in addition, create a sparkling and crackling effect on the target and, accordingly, acoustically improve recognition. Along with marking the hit point, it can suppress enemy fire due to this.

The universal projectile created in this way performs armor-piercing tasks, that is, the charge can penetrate armor, form fragments, and also create pyrotechnic effects on the target, such as burning, flashing and/or crackling.

The advantage of this solution is that it is possible to abandon secondary explosives, as well as an incendiary device or incendiary circles. Since the pyrotechnic warhead is activated even at low velocities of the projectile at the time of meeting the target, the problem of an unexploded projectile is small. Moreover, due to the use of pyrotechnic warhead, there are no classic cases with an unexploded projectile.

In the first embodiment, the pyrotechnic warhead is placed in the projectile body. It can be fixed in position with a plate, epoxy or something similar. Alternatively, the pyrotechnic warhead can be placed near the top of the projectile.

The second variant of implementation is found when a core is placed in the projectile. He can then fix the position of the pyrotechnic warhead. The core material may have a lower density than the projectile body, but this is not a requirement. Preferably, a metal or polymer material can be used.

In the third, preferred embodiment, the pyrotechnic warhead can be located between the projectile body and the penetrator. The warhead can be closed or sealed by a core, which in the preferred version also consists of a metal or polymer material.

In an improved version of this idea, the pyrotechnic warhead is placed around the penetrator. The shell of the projectile, which surrounds the pyrotechnic warhead, forms the necessary fragments after the warhead is activated.

Thus, a projectile with a new combat mass or warhead in the projectile body is proposed, preferably in the medium caliber range. When a projectile breaks, a shock wave is created, which leads to the formation of fragments or fragments, at least of the projectile body. At the same time, the warhead is activated due to the action of the shock wave,

So that the pyrotechnic warhead is transformed and the expanding gases of the pyrotechnic warhead additionally accelerate the surrounding fragments of the projectile shell. At the same time, the warhead is transformed without detonation, so it belongs to a different class of substances than traditional explosives. Ammunition disposal is, as a result, less expensive.

In addition, the reliability of maintenance of such ammunition increases. The side effect, in comparison with ordinary projectiles of the REGE type, increases. In addition, they refuse the secondary kit. The side effect of ammunition of the REG E type increases and leads to a less strong recoil at a longer firing range.

The invention is explained in more detail on the basis of an example of implementation with drawings in which the following is presented:

Fig. 1 first version of the projectile according to the invention,

Fig. 2 the next version of the projectile execution,

Fig. With the third version of the projectile.

In the presented in Fig. 1 version of the implementation of the projectile 1 contains the body 2 of the projectile, which has in the front part the top C of the projectile, also called the nose part or tip, and in the rear part the tail part 4 of the projectile. A pyrotechnic warhead 5 is placed in the shell 2 of the projectile. It can be fixed in its position with the help of a plate, epoxy resin 16 or something similar. In an alternative version, the pyrotechnic warhead 5 can be laid to the top of the projectile.

An alternative option is shown in Fig. 2. The pyrotechnic warhead 5 is placed between the core 6 and the shell 2 of the projectile 1. The core 6 is preferably made of metal or polymer material.

Fig. 3 shows a projectile 1 with a projectile body 2 and a penetrator 11. The projectile body 2 in this case also has the top of the projectile Z in the front part, and the tail part 4 of the projectile in the rear part. Penetrator 11, for its part, can be fragile. The pyrotechnic warhead 5 is placed between the projectile body 2 and the penetrator 11. In the preferred embodiment, the pyrotechnic warhead 5 is placed in a ring around the penetrator 11. At the same time, the warhead 5 can completely or at least partially cover the penetrator 11. The warhead 5 is closed by the core 6 and , thereby sealing.

At the same time, the core b is located, at least partially, on the penetrator 11. In the preferred version, the core 6 has a hole 15 into which the penetrator 11 can enter. This hole 15 is preferably matched with the external geometry of the penetrator 11. from metal or polymer material. With the help of the core b, the penetrator 11 can be fixed in its position in the shell 1 or in the shell 2 of the shell. Alternative location options for fixing the penetrator 11 are also possible.

The body 2 of the projectile and the top of the projectile can be connected to each other with the help of a threaded connection. Alternative connection options, for example, a pinched connection, are also possible.

The principle of its operation is as follows:

Due to the rupture of projectile 1 in the target, for example, in a metal plate, a known sound is generated

Reggae effect. At the same time, the shock wave is transmitted to the projectile body 2 and, if present, also to the core 6 (Fig. 2) and the penetrator 11 (Fig. 3).

The shock wave acts, on the one hand, on the shell of the shell 2, the projectile with the formation of fragments (not shown in more detail). Further, at the expense of this shock wave, as a result of adiabatic compression, the pyrotechnic set 5 or the pyrotechnic warhead 5 are simultaneously activated. As a result, the reaction temperature or the reaction threshold of the oxidation-reduction system, that is, the warhead 5 (pyrotechnics), are exceeded. War mass 5 reacts directly. After that, the expanding gases of the pyrotechnic warhead 5 additionally accelerate, for their part, the surrounding warhead 5 and the fragments of the casing shell 2 of the projectile formed due to the shock wave when the projectile bursts in the lateral direction.

War mass 5 can also be understood as several pyrotechnic sets that create a burning, sparkling and/or crackling effect on the target.

The advantage is that the resulting cone of fragmentation (opening angle of the cone) of fragments of the casing of the shell 2 of the projectile is constant, since it does not depend on the firing range (velocity of the projectile at the time of meeting with the target).

The shell 2 of the projectile can be additionally provided with places of specified destruction along the perimeter (not shown in more detail). In this case, they can contribute to the formation of fragments of projectile 1. Also, due to the presence of predetermined destruction sites, fragments of the shell of the shell 2 of the projectile can be better determined by their sizes.
